BV data in int_32 format?

[olafdimigen]

Exported epoched data from BV-Analyzer and would like to read them in with pop_loadbv.
But exported data is in int 32-bit format, which is not supported by pop_loadbv.

[Binary Infos]
BinaryFormat=INT_32
UseBigEndianOrder=NO

Any solution for this? I did not see an option to change export bit range in BVA or to export as float-32.
Any input appreciated.

Would you mind sharing a file. We will add support if it not too difficult.

Thanks! Here is a file. Epoched data was apparently exported using Analyzer's GenericDataExport.

Would it be OK to add it to our test cases?

[olafdimigen]

Since it's collaborator data (not my own), I am unfamiliar with exact restrictions, would be better if not added to unit testing cases (sorry)

[arnodelorme]

OK, thank you. Ramon said he would look into it in the next few weeks.

I had the same issue. I think the problem would be solved by adding here

bva-io/pop_loadbv.m

Line 103 in a61a74a

case 'ieee_float_32', binformat = 'float32'; bps = 4;

the line
case 'int_32', binformat = 'int32'; bps = 4;

4years later, same issue. why is this line not added to the function natively?

[arnodelorme]

We do not have a test file. Would you mind to add the line test and do a pull request? It is easy, you can edit this file

bva-io/pop_loadbv.m

Line 103 in a61a74a

case 'ieee_float_32', binformat = 'float32'; bps = 4;

using the edit button, add the line, then clone the repo and make sure it works with your file. I have talked to Brain Products at OHBM 2026, and they might take over the support of this plugin @nucleuscub
